CHARLES E. KLAITS, OF ST. LOUIS, MISSOURI, ASSIGNOR TO HARRY I4. HUSSMANN REFRIGERATOR SOURI.

COMPANY, OF ST. LOUIS, MISSOURI, A CORPORATION OF MIS- SHOW-CASE REFRIGERATOR.

Application filed January 11,1926. Serial No. 80,459.

This invention pertains to show case refrigerators and more particularly to means for draining same.

Most modern types of show case refrigerators are provided with one or more brine pans located in the bottom of the refrigerator and receiving the drip from the freezing mixture container. This brine is eventually drained into a trap through which it is discharged from the refrigerator. In the ordinary construction of such a trap the outlet for the water passes directly downwardly through the bottom ofthe refrigerator. Accordingly, in order to carry off the water, connections must be made to this trap and such connections mustpass through the floor so as to carry the water to a suitable drain. This construction necessitates, therefore, expensive plumbing work in making connections to the drain.

One of the objects of this invention is to provide an outlet adapted to drain a refrigerator of this kind which will obviate the necessity of passing the drain connections through the floor.

Another object is to provide such an outlot which will be simple in construction and easily connected to the drain.

Further objects will appear from the following description taken in connection with the accompanying drawings, in which Figure 1 is a perspective View of a show case refrigerator embodying this invention.

Figure 2 is an enlarged perspective view of an outlet constructed in accordance with this invention, and

Figure 3 is a section on line 3-3, Figure 2.

Referring to the accompanying drawing, 1 designates a show-case refrigerator of the double icer type having compartments 2 for the freezing mixture containers and a central compartment provided with transparent panels for storing the material to be cooled. Brine pans 4 are located in the bottom of the compartment 3 and are arranged to overflow into the outlet designated generally by the numeral 5. I

Figures 2 and 3 show the construction of this outlet. This comprises a gathering bowl 6 having a sloping bottom 7 and an upright vertical wall 8. The bowl 6 is arranged to be set in a suitable depression in the floor 9 of the refrigerator and is set in such a way that its vertical wall 8 is positioned against a vertical wall 10 of the refrigerator. I

The vertical wall 8 is perforated with an opening adapted to admit a drain pipe 11 and is provided with a suitable threaded bushing 12 to which said pipe may be connected. The pipe 11 is arranged to pass through the vertical wall 10 of the refrigerator to the outside thereof. Arranged so as tocover the opening in the vertical wall and the end of the tube 11 is a hood or upright conduit- 13 closed at the top and extending downwardly to within a short distance of the lowermost part of the bottom 7. A. small gap 14 is left between the bottom of the conduit 13 and the bottom of the bowl 6 so as to permit water to flow into the conduit 13 and at the same time prevent the entrance thereinto of an excessive amount of dirt or foreign matter. This gap 14 may be made in the form of a narrow slit by forming the end of the conduit 13to a bevelled form parallel with the bottom 7 as shown in Figure 3.

The bowl 6 being depressed below the fioor of the refrigerator is adapted to collect moisture and drippings, such as often accumulate on the floor of such a device. The brine pans 4. are also arranged to overflow into the bowl 6. Said pans may be provided with laterally extending overflow spouts 15 arranged to extend over the bowl 6 so as to discharge there into. The discharged water will, therefore, collect in the bowl 6 and rise in the conduit 13 to be discharged through the pipe 11. A certain amount of water will always remain in the conduit 13 and since the latter is closed at the top entrance of air to the refrigerator through the pipe 11 will be prevented.

It will be noted that since the pipe 11 emerges from the refrigerator at the side or back thereof. and in a. horizontal direction, connections therefrom to the drain can be made conveniently above the floor. There is, therefore, no necessity for cutting the floor to pass a drain pipe therethrough and all the drain connections are accordingly simplified. It is possible, therefore, to save considerable expense in the installation of such a refrigerator by making drain connections in accord ance with this invention. Furthermore, a refrigerator of this type is occasionally moved from one place to another. When such move ment is made it is unnecessary with the pres cut invention to make new openings in the floor and rearrange pipes in the story below.

It will also be noted that putting the trap in the middle and at the back wall removes it from a. position underneath the drip pans and renders it easily accessible for cleaning and the like.

It is obvious that various changes may be made in details of construction without departing from the spirit of this invention; it is, therefore, to be understood that this invention is not to be limited to the specific details shown and described.

Having thus described the invention, what is claimed is:

1. In a showcase refrigerator, a drip outlet, comprising. a gathering bowl below the floor level of the show case and having an upright wall adj acent a wall of the refrigerator, a conduit rising from the bottom of said bowl and along its wall. and a lateral outlet for said conduit passing through the wall of the bowl.

2. In a show-case refrigerator, a drip outlet, comprising, a gathering bowl having a. bottom sloping downwardl from the door of the show case, an upright conduit rising from a. lower part of said bottom to a point adjacent the refrigerator wall, and a lateral outletfor said conduit passing through said wall.

3. In a show-case refrigerator, a. drip outlet, comprising, a gathering bowl having a sloping bottom and an upright wall adjacent a wall of the refrigerator, a conduit rising from a lower part ofi said bottom and along its wall, and an outlet for said conduit passing through the wall of the bowl.

4. In a show-case refrigerator, a drip outlet. comprising, a gathering bowl having a bottom sloping downwardly from the floor of the show case and an upright wall adjacent a wall of the refrigerator, an upright conduit rising from the bottom of said bowl, and a lateral outlet for said conduit passing through said wall.

5. In a show-case refrigerator. a drip outlet, tomprising, a gathering howl having a bottom sloping downwardly from the floor oi the show case and an upright wall positioned against. the wall of the refrigerator. a conduit rising from the bottom oi said bowl and along said wall, a lateral outlet for said conduit passing through said walls. and a drip pan having an overflow adapted to dist-barge into said bowl.

6. In a show-case refrigerator. a drip outlet comprising, a gathering bowl having a bottom sloping downwardlv to the rear wall of the refrigerator, a vertical rear wall [or said bowl positioned against the rear wall of the refrigerator, vertical side walls for said bowl. a conduit rising from near the bottom of said bowl along the rear all thereof. and an outlet pipe communicating with said conduit and passing through the rear walls of said how] and the refrigerator.

7. In a show-case refrigerator, a drip outlet comprising. a gathering howl having a bottom sloping downwardly to the rear wall of the refrigerator, a vertical rear wall for said bowl positioned against the rear wall of the refrigerator, vertical side walls for said bowl. a conduit rising from near the bottom of said bowl along the rear all thereof. an outlet communicating with said conduit and passing through the rear wallol said bowl and the refrigerator, and a drip pan positioned to overflow into said bowl.

In testimony whereof I atlix my signature this 6th day of January, 1926.
